Species 11. (Mus. Ciimiug.) 



ZlZiPHlNUS SPLENDIDUS. Zizi/pli. testd mhaeute conicd, 

 iimudinscuM, ntifractlbus convexo-decUmbus, undiqne 

 regulariter grauo-liratis ; alhldd, auraidio-flavo et pur- 

 pureo-roseo undiqne varieyatd et nmculatd. 



The splendid Zizyphinus. Shell rather sharply co- 

 nical, somewhat swollen, whorls eonvexly sloping, 

 regularly grain-ridged throughout; whitish, varie- 

 gated and spotted throughout with orange-yellow 

 and purple-rose. 



Philippi, MS. in Mus. Cuming. 



Hub. Australia. 



In colour this species partakes very much of the cha- 

 racter of the preceding, the purple-rose being more con- 

 spicuous, and broken up into blotches. The shell is of 

 rather a lighter, more tumid growth, with the basal ridge 

 no more prominent than the rest. 



Species 12. (Mus. Cuming.) 



Zizyphinus jujubinus. Zizypli. testa pyraniidali-conicn, 

 solidiusculd, anfractibm concavo-declivibus, deinde tu- 

 nddo-rotuiidatla, nndique (jrmiath, granis parvis, sub- 

 distantibiis ; figliiid, aiifractuum parte inferiors satii- 

 ratd, albo-Jlammald, basi minute albo-piuictatd. 



The jujube Zizyphinus. Shell pyramidally conical, 

 rather solid, whorls concavely sloping, then tumidly 

 rounded, everywhere grained, grains small, rather 

 distant ; brick-red, lower part of the whorls darter, 

 flamed with white, base minutely white-dotted.

 Tnchus Ze:i/phinus, Chemnitz. 

 Zizyphinus jujubinus, Adams. 



Hab. Swan Kiver. 



Of rather solid growth, minutely granuled, the lower 

 part of each whorl tumiiUy bulging, and flamed with 

 white. 



Species 13. (Mus. Cuming.) 



Zizyphinus annulatus. Zizyph. testd subacute conicd, 

 tenuiculd, anfractibus eonvexo-planatis, eximie grano- 

 liratis, interstitiis subexcavatis, aureo-flavd, ad mar- 

 ginem basalem anfractuum vivide caruleo-purpured, 

 liris purpureo-sangidneo minute punctatis. 



The kinged Zizyphinus. Shell rather shai-ply conical, 

 somewhat thin, whorls eonvexly flattened, delicately 

 graiu-ridged, interstices rather excavated ; golden yel- 

 low, brightly stained with blue-purple round the 

 basal edge of each whorl, ridges minutely dotted with 

 purple-blood. 



Tnchus annulatus, Martyn, Univ. Conch, vol. i. f. 33. 

 Trochus virgineus, Chemnitz. 

 Zizyphinus annulatus, Adams. 



Hab. Monterey, California. 



This well-known species is remarkable for the clear de- 

 finition and constancy of its painting — a bright golden 

 yellow, encircled with minutely red-dotted gi'ained ridges, 

 bordered with a clear blue-purple band winding round the 

 basal margin of each whorl, from the apex to the aperture. 



Species 14. (Mus. Cuming.) 



Zizyphinus castiia. Zizyph. testd late conoided, de- 

 pressd, acutanguld, tenuiculd, aiyfractibus plano-decli- 

 vibus, spiraliter lineari-incisis, infra suturas oblique 

 plicato-crenulatis, ad marghiem basalein funiculatis ; 

 pallide earned, obscure tessellatd et articulatd. 



The camp Zizyphinus. Shell broadly conoid, depressed, 

 sharp-angled, rather thin, whorls flatly sloping, spi- 

 rally linearly engraved, obliquely plicately crenulated 

 below the sutm-es, corded at the basal margin ; pale 

 flesh-colour, obscm-ely tessellated and articulated. 



Hab. Swan River. 



Chiefly remarkable for its light, broadly depressed form 



and almost total absence of sculptiu-e.
